Neosabellides lizae: A new species of Ampharetid Worm from Lizard Island on Australia's Great Barrier Reef.

Ampharetid Worms are small, usually marine, Annelid Worms related to the tube-building Trumpet Worms and the Alvinellid Tube Worms found living around hydrothermal vents. They are small infaunal Worms, living in burrows in mud, sand, or other unconsolidated sediments and feeding by ingesting sediment and digesting organic material within it.

In a paper published in the journal Zootaxa on 18 September 2015, Tom Alvestad of Uni Research and Natural History Collections at the University Museum ofBergen and Nataliya Budaeva, also of Natural History Collections at the University Museum of Bergen, and of the P.P. Shirshov Instituteof Oceanology of the Russian Academy of Sciences, describe a new species of Ampharetid Worm from sediments off Casuarina Beach on Lizard Island on Australia's Great Barrier Reef, close to the LizardIsland Research Station of the Australian Museum.

The new species is placed in the genus Neosabellides, and given the specific name lizae in reference to the area where it was found. The worms are 3-5 mm in length, and a metalic silver grey in colour. They each have 26 thoracic segments and 14 abdominal segements with paradopodia (limbs) and one pair of eyes on the head.
